Just purchased a used VC Radiance set up for LP. Fingers crossed this thing will fire once I get it all hooked up. My question relates to direct vent piping. I just purchased an "up and out" kit for a horizontal termination. This will be on a vinyl sided house. The kit did not come with a vinyl siding standoff. Can I use the supplied termination cap, or do I need to include a standoff in between the siding and the cap? Anyone else with experience on this? Or any feedback, good - bad - or ugly - on the VC Radiance?
